DOCKER+DENO episode 2: Containerize a Deno FULL REST API from Traversymedia Deno Crash course

#deno #api #docker #100daysofcode

To follow Please check the Deno crash course by Traversymedia

Deno is the buzzword of the moment, and we still don't know how it will end.

Honestly, I am a fan of node, but I was intrigued, after following the Deno Crash Course, by Traversymedia I tried to containerize it with docker.

Warning!
this example is based on this docker image https://hub.docker.com/r/hayd/deno

Which is not an official deno repository

Github Repository: https://github.com/FrancescoXX/deno-docker-api

JUST TEST

docker run -it --init -p 8000:8000 --init francescoxx/deno-docker:0.0.2

Short version

you can just clone the repository

git clone https://github.com/FrancescoXX/deno-docker-api

navigate to the folder where the docker-compose.yml is located, and run

docker-compose up --build

Done!

Long version

If you want to follow along, and you use Visual Studio Code, I suggest you install this extension:

Step 1

Follow the traversymedia Deno Crash course
https://www.youtube.com/watch?v=NHHhiqwcfRM

Step 2

then, we create a very simple Dockerfile, using the hayd/alpine-deno:1.0.0 image

FROM hayd/alpine-deno:1.0.0

EXPOSE 8000

WORKDIR /app

USER deno

COPY . .

CMD ["run", "--allow-net", "server.ts"]

STEP 3

And last, we create a very simple docker-compose.yml file, which is no needed for now, but it could be useful in the future, for example, if we start using a database or some other services

We define port 8000 as both inner and outer one and a default network

version: "3.7"

services:
  deno:
    image: "deno-docker:0.0.2"
    build: .
    ports:
      - "8000:8000"
    networks: 
      - deno

networks:
  deno: {}
